01/12/2010  It is reported that fine aggregate of limestone can reduce the drying shrinkage in concrete. Mix proportions of fine aggregate were varied as listed in Table 4. Except the ratios of fine limestone and mountain sand, the amount of other materials of cement and coarse aggregate kept constant. Table 5 shows all mixture proportions of concrete.
